High-performance computing (HPC) clustering
High-performance computing (HPC) cluster technology is used in supercomputers (multiple computers working in parallel and acting as one computer to achieve very high calculating power). Unlike failover-clusters, HPC-clusters do not require shared disk as it only does calculations and does not need to read or write to a common storage. If one of the machines in a HPC-cluster fails, then all that happens is that the cluster as a whole can not calculate as fast but none of the functionality is lost. Microsoft Windows Compute Cluster Server 2003 (CCS) is a such cluster technology software, announced in June 2006 by Microsoft,[2]
